402,000 Mile E55 AMG dyno test. Here's how much power it made.

The 402,000 mile Mercedes-Benz E55 AMG is back at Sound Performance for revenge. It broke on the dyno last time and we weren't able to get good dyno numbers. Its all fixed up and in this video you see exactly what 400k miles does for power on a hand built AMG engine.
Thanks Sound Performance for the dyno time.

[@Twobarpsi]

So roughly 29 horsepower less than stock, but dynoed on a 90-degree day! I say it makes exactly the power it should. Wow I love Mercedes-Benz!

[@Josh-hr5mc]

This goes to show what happens long term with a hand built motor vs a hurried up mass produced motor

[@diablocls55]

Hand built engines are also cool because.... you know who to blame when something breaks 😂 jokes aside you just can't beat a Mercedes, especially an AMG. Untouchable. AMG for life

[@joshd9454]

[@TitaniumCountess]

The E55s are bulletproof. They are the best super sedan of the entire 2000s if you want to judge on practicality and reliability. All Mercedes with the M113 engine are bulletproof... I'm on my third E55, my first W211 (first were W210s)... My first W210 sold, on the original engine and transmission, with 305k miles on it. Ran like it did the day I bought it. My second one had its life cut short by a Cadillac Escalade rear ending it on the 405 in Santa Monica, and it was replaced with a W211 which now has 150k miles on it. I intend to run it to 300k, and there's nothing that indicates to me that the car won't be able to do that without issue. The W211 E55 is the simplest of the "super sedans" of that era by a very wide margin. You've got a stout single cam V8 with no variable timing and very little high tech wizardry. Just good old fashioned horsepower mated to an impossible to kill 722.6 transmission, the same unit that was used in the S65/SL65/CL65 AMG V12 cars that made nearly 800 torque... the 722.6 can take that and be reliable for years on end, then I can surmise it's hardly breaking a sweat at 516 ft-lbs of torque. Great cars, with so much less to go wrong than the competition - which was the E39 M5 (2003), E60 M5 (V10 nightmare engine, SMG semi-auto nightmare clutch), the C5 Audi RS6 (bespoke 450 horsepower twin turbo V8 with 4 radiators, and a requirement to drop the engine out of the car every time you need to do /any/ maintenance to the engine, and mated to a ZF 5 speed auto that can't handle the power), the C6 Audi S6 and RS6 (Lamborghini Gallardo 5.2 V10, same issues as the C5 - engine out for anything, and ZF 5 speed auto that can't take the power), and perhaps the first gen Cadillac CTS-V if you want to include that (broken motor mounts *constantly* and any hooning around and the differential blows up)... that was the competition of its day. The E55 is lightyears ahead of them in reliability. They're simple to run, cheap to maintain (very few AMG specific parts to the engine - most of it is standard M113 from an E500), and cheap to fix when they do break.

[@martinhuusfelt1783]

Yep tranny is build for a 1000NM was used for all Mercedes up to 2007 that for a reason :) Bullet proof if just fluids are replaced else it dies and it dies really badley hahaha. Love my E55 AMG 2004 LOVE IT a real beast had it for 7 years I drive it to the end of my days trust me

[@zackmatulis4094]

I bought my W220 S500 on a whim with 240 thousand miles on the odometer a few months ago and it runs like a top. Only problems I've had are old flex discs needing replacement after some thrashing. The car doesnt blow smoke, feels powerful as all hell, and sounds fantastic with open headers. I want to take it to half a million miles but I'm thinking the timing cover o rings ought to be looked at along with the plastic tensioners. Once those o rings go it's all over for the crank bearings. I'd love to see it hit half a million on stock head gaskets and piston rings!

[@armiragneis9608]

First of all - thank you for your great channel! It has helped me A LOT! I am about to buy a 160 000 miles W211 E 55 AMG. Please excuse me for the noob question, but I have no knowledge regarding cars. I just like to ride them and pay to people to maintain them. Should I expect a loss of some HP at this stage? And if some HP are lost, can I "restore" them by changing something under the hood?

[@ahemgee9542]

Spot on

[@johnnygaffigan3090]

Im looking to get one but the market is so fucked rn. Waiting for market to hopefully chill out so these are more affordable again. Is it a good idea to have low miles? I dont like the idea of a car sitting and it hard to find a high mileage well maintained one in Virginia. If one hasnt been maintained well can you preserve it by proper maintenance or do you need it meticulously handled all the time. Dont really want a money pit on an older car but Im absolutely in love with it

[@frank09busa]

owner need to be credited big time for this since he's the one had it maintained in such an awesome condition

I wish I knew who he/she was. It was acquired by a small dealer near my house.

216000 miles on my 2006 E55, replaced an alternator, front electro hydraulic shocks, free gas tank a couple of years ago from Mercedes and free SBC pump a month ago from Mercedes. I love my beast and there is nothing out there that I want to replace it with.

[@koachk5360]

Incredible that the engine output has remained the same even after 400,000 miles!

[@Kilo-Mike]

Loved the video. I have a 3x Benz's 38yrs old 300SD 300K, 16yo E320 349,000Miles on it, and 2001 S55 AMG M113 150,000miles. I'm one of those hardcore home mechanic's, but I never opened the top end on the M112 and M113's engines. The 300SD diesel i had to perform routine valve adjustments every ~100K. None use oil. The old school OM617 diesels and M112,M113 engines are the most reliable engines every manufactured in history. The M112,M113 engines have a special silicone crystal lined aluminum cylinder/block that was polished like glass, acid etched to remove aluminum particles and leave behind only the hard silicone, then polished again. And everything else is polished and forged. all have 8Liters if oil which is probably another reason they last so long, always getting plenty of fresh cool oil. They use a sophisticated thermoconductivity sensor to monitor oil condition and tailor change intervals according to specific driving conditions, not predetermined mileage intervals. Usually my oil changes have been every 10-12K miles. They all have the 722.xxx variant 4spd (300SD) and 5spd (E320,S55) automatic transmission is also the best transmission in the world. The transmission is still built and used in many production and race cars around the world today.

The Mercedes M113 AMG cars are highly underrated, durable beasts

[@DuBstep115]

yeah and M104 is better engine than 2JZ

[@kbcarroll]

DuBstep115 i keep waiting for someone to figure out that if you machined all the same shit for an m104 as you would a 2jz, you could biturbo it every bit as well and uncover an untapped mountain of good straight 6 motors in junk yards all over the world. Russians are getting up to 800hp with stock internals

[@PanzieLol]

Its too bad theres no aftermarket for the m104 besides TurboBandit... and probably some phillipines people

[@jrt2924]

Evroz621 turbobandit prices arent really that bad sure it's a shame there isnt "ebay" tuning parts but even the stock internals are crazy strong

[@PanzieLol]

JRT its true that they are high quality, so that justifies the price. But i do wish there was nothing more competition such as ebay parts. Like you compare a bmw of the same gen, like the e36 and theres loads of stuff. Its similar with the w211 e55s and other m113k engine cars, theres VRP speed shop which is clearly well known and quality, but also not cheap

[@Diordna11]

Unless you drive in a heavy rain and get a big splash from an oncoming vehicle like AutoVlog. His C63S just Hydrolocked. Maybe LSC can chime in and explain how something like this can happen to a car like this. I would be afraid to drive in the rain again if I had that car. I could understand if the engine got partially submerged, but it sure doesn't sound like that. I feel bad for the guy because the diff went out first with only a few thousand miles on it and now this. Check out his video on this mishap.

[@YUSKHAN]

HEKTIC458 no the motors are not bullet proof, the m113k is known for blown piston rings

I don't know if most cars will last 400,000 miles but I feel most should last 200,000 miles, with gentle care and dealer maintenance. Most of this is all on the type of ownership the vehicles have had.

[@iAlwaysSpeakTheTruth]

Gregory Trane I would be careful with dealer maintenance... a reputable Indy shop is a better direction. Some dealerships aren't out to help you but make money any way possible.

[@gregorytrane7828]

Joey McMahon Jr It all depends on the dealer. Consumers can always file complaints to the corporate headquarters. Something dealers don't want, as well as other avenues of correction. With independent garages or dealers, you're in a situation with limited legal resources that can be more time consuming if there is a problem. I've always had better luck with authorized dealers. But if independent dealers or garages work for others, that's OK too.

[@777jones]

I agree it depends on the dealer. Plenty of dealers have superior knowledge to an indy shop and are priced equally. In other cases, you get a superior indy shop and a crook dealer. But in general a dealer's best tech is superior to the indy shop. Just my 2c on it.

Mercedes never dies

[@AMGmeister]

Is the car in dyno mode? It dosen't sound like its revving close to 6100rpm where the car makes peak power (about 410+whp). Clearly this is a healthy E55 since there is 450wtq + 18% = 531lb-ft. Needs to rev higher. You should be making 400+whp.

[@LegitStreetCars]

Yes in dyno mode. Not sure if its the way this dyno is loaded but about 5500 rpm is all we could get on those super long pulls. I agree a pull in the 6k range would have likely produced even more power. Alex

[@whyzee125]

I'm not familiar with e55's dyno numbers but mustang dyno's do read lower than dynojet or dyno dynamics

[@AMGmeister]

There are youtube videos of stock E55's doing 414whp / 453whp on a mustang dyno.

[@11094DEREK]

bullet206 Yeah those 400hp ones probably have 40k lol

[@ferrumignis]

sam spezza: It quite obviously can not be a fixed horsepower number, though neither is it a fixed percentage. If a transmission has a fixed loss of (e.g.) 38bhp, that would mean the engine would have to make more than 38bhp just to get the wheels turning, which is clearly stupid. Losses increase with increasing engine speed and torque, though not in a linear manner.
